To provide a locking/unlocking system using inexpensive radio communication with high security. When a locking/unlocking operation is performed in remote controller (200), it is indicated to intercom master device (100) via encrypted communication that the locking/unlocking operation is performed, and electric lock (110) is locked/unlocked according to the operation performed in remote controller (200). Further, remote controller (200) transmits an unencrypted message to intercom master device (100) at prescribed intervals. When there is no communication with remote controller (200) for a prescribed length of time, intercom master device (100) locks electric lock (110).
